SC-412 specifications

The QSC Audio SC-412 is a high-performance loudspeaker designed specifically for professional audio applications. With its robust construction and advanced technologies, it delivers excellent sound quality, making it a popular choice for live performances, installations, and event spaces.

One of the standout features of the SC-412 is its powerful driver configuration. It includes two 12-inch direct-radiating woofers that provide deep, punchy bass response, complemented by a 1.75-inch exit compression driver mounted on a high-frequency horn. This configuration ensures a wide frequency range, enabling the SC-412 to reproduce everything from subtle vocal nuances to explosive rock guitar riffs with clarity and depth.

A key technology used in the SC-412 is QSC's proprietary Directivity Matched Transition (DMT) design. This advanced engineering approach ensures consistent directivity across the frequency range, providing even sound coverage in various acoustic environments. As a result, audiences experience a balanced and immersive listening experience, regardless of their position in the venue.

The cabinet construction of the SC-412 further contributes to its performance. It is built from durable, ply-birch wood and features a rugged finish, enhancing both aesthetics and durability. The enclosure is designed to minimize resonance, delivering accurate sound reproduction while ensuring that the cabinet itself does not color the audio signal. Additionally, the SC-412 includes a rear rigging point, making it easy to install in various orientations, whether flying or on a stand.

In terms of connectivity, the SC-412 features both speakON and binding post connectors, offering versatility for various setups and ensuring compatibility with a wide range of amplifiers and mixers. The loudspeaker's nominal impedance of 8 ohms allows for flexible system design and configuration.

The QSC Audio SC-412 is an excellent choice for audio professionals seeking reliability and performance. Its advanced features, like the DMT design and high-quality components, make it suitable for demanding applications in both live sound and fixed installations. With its ability to deliver powerful, clear, and consistent audio, the SC-412 stands out as a versatile solution for sound reinforcement needs. Whether used for concerts, corporate events, or permanent installations, it delivers the quality and reliability that audio professionals have come to expect from QSC.
